Re: [Help-smalltalk] Re: IO and Process Scheduler

Moin Paolo Bonzini,

> What OS are you using?  The scheduler works under Linux and MacOS at least.

  smalltalk-2.1.10 on a Debian Sarge system running Linux 2.6.11.7
  skas3-v9-amd32 kernel.
  
  Take a look at, www.copyleft.de/Parla/GST-Network.st and try:

loader.st
  Namespace current: Smalltalk!
  PackageLoader fileInPackage: 'TCP'!
  Smalltalk addSubspace: #MUD!
  Namespace current: MUD!
  FileStream fileIn: 'GST-Network.st'!
  Namespace current: Smalltalk!

  to start it :

      st> MUD.MUDServer new port: 4321; start!
      'register server socket'
      'waiting for connection'
      MUDServer new "<0xb3d54b10>"

  now `telnet localhost 4321` - but nothing happens, if you type
  something - the accept is blocked by console, besides using
  forkAt: - now type something in smalltalk :

      st> 1!
      'accepting connection'
      '>$t'
      '>$e'
      '>$s'
      '>$t'
      '>$
      '>$
      '
      'waiting for connection'
      1
      st> 

  replacing start at the command line and in MUDServer>>run with run
  will provide a single process telnet server that works fine. Replacing
  start with run in the command line, but not in MUDServer>>run will
  create a funny situation. At first it works, so its possible to
  connect and even to type a line. But the next line is not read.
  The client process hangs waiting for IO that already arrived, till
  I open a fresh connection to trigger something in the main process.
